This radial bar chart displays the population of Maryland counties, segmented by age cohorts. The visualization uses a circular layout where each county occupies a radial band, with the length of each segment representing that cohort’s population contribution. Built with D3 v4, it employs `d3.scaleBand` for angular positioning, `d3.scaleRadial` for radial distances, and `d3.arc` to render the stacked segments. The data is loaded from a GitHub-hosted CSV file, and the chart includes circular gridlines, county labels, a population axis, and a color-coded legend for the age groups.

MD Counties Radial Stacked Bar

A radial stacked bar chart displays the population of Maryland counties partitioned by age group. Each county occupies one annular sector, with the length of each colored segment representing the population count for a specific age bracket. The chart uses D3 v4 APIs including `d3.scaleBand` for angular positioning, a custom `d3.scaleRadial` for radial scaling, `d3.arc` for path geometry, and `d3.stack` to build stacked segments. Data is loaded from a CSV file containing county-level population figures, rendered as SVG, with a legend identifying the age categories.

MD Counties Stacked Bar Chart

This stacked bar chart displays the population of each Maryland county, broken down by age group. The chart sorts counties by total population and uses a color-coded legend to distinguish seven age cohorts. Built with D3 v4, it loads CSV data from a GitHub repository and renders the visualization as SVG. The code implements d3.stack(), d3.scaleBand(), d3.scaleLinear(), and d3.scaleOrdinal() to generate the stacked bars, axes, and legend.

MD Counties Race Radial Chart

This radial chart visualizes the racial composition of counties in Maryland, with each county represented as a segment ring spanning 360 degrees. The height of each stacked ring segment reflects the population count for each racial category, using color-coded layers. The visualization is built with D3 v4, leveraging `d3.scaleBand` for angular positioning, `d3.scaleRadial` for radial distances, and `d3.stack` for the stacked data series. Data comes from a CSV file hosted on GitHub, and the chart includes labeled county names, radial gridlines, population ticks, and a legend.

Bar Maryland Counties

A bar chart displays the population of Maryland’s counties, sorted by name, with hover effects turning bars brown. The chart uses an SVG rendered with D3 v4, employing `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis, which is formatted as percentages. County population data comes from a CSV file pulled from a GitHub repository, with axis labels rotated for readability. The visualization includes a title and a source note.

MD Counties 4

An interactive choropleth map of Maryland counties displays population density using a sequential color scale, with hover effects revealing county details. A donut chart in the corner dynamically updates to show population, land area, and density proportions for the selected county. Built with D3 v4, the visualization uses `d3.geoConicConformal` for projection, `d3.geoPath` for rendering shapes, and `d3.pie`/`d3.arc` for the chart. Population data is sourced from JSON files, while county boundaries come from TopoJSON.

Radial Stacked Bar

A radial stacked bar chart displays population distribution across U.S. counties by age bracket, arranged around a circular axis to emphasize potential cyclical patterns, though the data is not cyclical. The visualization uses D3 v4 with a custom `d3-scale-radial.js` plugin implementing a square-root scale for the radial variable, while `d3.arc()` generates the annular segments with `d3.stack()` for layered series. State labels rotate around the perimeter, and circle gridlines with tick marks indicate population totals. Data loads from a CSV file, rendered as SVG in a 960×960 viewport.

MD Counties

A choropleth map of Maryland counties colors each county by population density using a threshold scale and the d3.schemeOrRd color scheme, with county boundaries derived from a TopoJSON file. Hovering over a county highlights it with a thicker stroke, displays its name, population, land area, and density in an info box, and renders a small pie chart using d3.pie and d3.arc showing the county's population, land area, and density. The map uses a d3.geoConicConformal projection, along with topojson-client to parse geographic data and d3-scale-chromatic for colors.

Radial Stacked Bar

This radial stacked bar chart displays the age distribution of each U.S. state’s population as concentric arcs. The visualization uses a d3.radial scale to map population totals from the inner to outer radius, while d3.stack and d3.arc render the stacked segments between angular bands. State labels rotate around the circle, and circular gridlines mark population tick values. The data comes from a CSV file, rendered as SVG using D3 v4.
